Bath products have become more minimalist in design, and now kitchen sinks are following the trend. The Peak Series blends angular design with a more useful flat sink bottom. Moreover, it features a drain cover that acts as a second strainer while maintaining the flat surface of the sink. A variety of accessories, such as an iroko cutting board, is available.
